Minimally invasive repair of a valve leaflet in a beating heart
First Claim
Patent Images
1. A valve repair device with a replaceable suture cartridge for repair of a valve leaflet in a beating heart of a patient, comprising:
- a valve repair device including a main shaft with a proximal end outside the patient and a distal end adapted for insertion into the beating heart of the patient, a handle with an actuator operably connected to the proximal end of the main shaft, a capture assembly operably coupled to the distal end of the main shaft including a first portion of a jaw assembly adapted to grasp the valve leaflet in response to selective actuation of the actuator, and a needle head slidably positionable within the capture assembly to penetrate the valve leaflet and draw a suture through the valve leaflet, the main shaft further including an outwardly exposed cartridge channel extending longitudinally along substantially all of a length of the main shaft on an outwardly facing surface of the main shaft; and
a replaceable suture cartridge including a secondary shaft having a distal portion including a second portion of the jaw assembly integrally couplable to the capture assembly and a proximal end releasably couplable to the handle and the actuator, the secondary shaft being adapted to be slidingly engaged by a substantial portion of the length of the cartridge channel along a substantial portion of a length of the secondary shaft such that the main shaft and secondary shaft can be longitudinally displaced with respect to each other by sliding the secondary shaft along the cartridge channel and the actuator is actuatable to selectively position the second portion of the jaw assembly along a longitudinal axis of the capture assembly, the replaceable suture cartridge including a suture channel extending longitudinally along an exterior surface of the secondary shaft within which the suture is carried such that the suture extends out of the replaceable suture cartridge adjacent a proximal end of the secondary shaft, the main shaft at least partially covering the suture channel when the secondary shaft is slidingly engaged with the cartridge channel, and the suture having a loop portion presented proximate the jaw assembly when the replaceable suture cartridge is engaged with the valve repair device.

Abstract
A valve repair device with a replaceable suture cartridge for repair of a valve leaflet in a beating heart of a patient includes a valve repair device and a replaceable suture cartridge. The valve repair device can include a handle with an actuator, a capture assembly including one portion of a jaw assembly adapted to grasp the leaflet and a needle head for penetrating the leaflet. The replaceable suture cartridge can include a secondary shaft including a second portion of the jaw assembly integrally couplable to the capture assembly and a channel within which a suture is carried.
